Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to an integrated dryer. Background Art

[0002] At present, each component in the dryer is integrated into the same device to make an integrated dryer. The integrated dryer integrates the drying function and the moisture exhaust function. According to the integrated dryer, a drying room is built, and the drying room only needs to provide a closed space to realize the various functions of the integrated dryer. Therefore, the structure of the drying room supporting the integrated dryer is relatively simple. The integrated dryer is provided with an air outlet and an air inlet. The hot air flow blown out from the air outlet flows through the entire drying room, and then the hot air flows back into the integrated dryer through the air inlet. After the hot air flow passes through the material, part of the heat will be dissipated, and a low-temperature area will be formed at the position close to the air inlet inside the drying room, and the drying effect of the material in the low-temperature area is poor. For this reason, if the fan at the air inlet and the fan at the air outlet are set to rotate forward regularly and reverse regularly, so that hot air flowing in two directions circulates in the drying room at different times, a low-temperature area in the drying room can be prevented from being formed.

[0003] However, the integrated dryer also has a moisture exhaust function. Since the structures of the internal circulation air duct and the moisture exhaust air duct of the integrated dryer are fixed, when the moisture exhaust function is turned on, there is a large difference in the flow rate of the hot air flowing in different directions in the circulation air duct entering the moisture exhaust air duct, resulting in a large difference in the moisture exhaust effects of the hot air flowing in two directions, which affects the moisture exhaust efficiency of the drying room. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems existing in the prior art. For this purpose, the utility model provides an integrated dryer, which can make the moisture exhaust effects of the hot air flowing in two directions inside the integrated dryer relatively similar and improve the moisture exhaust efficiency of the drying room.

The fourth fan inhales the dry air from the outside into the second chamber through the fresh air channel and flows to the first chamber through the third air outlet. Since heat exchange is carried out between the fresh air channel and the moisture exhaust channel, the dry air absorbs the heat of the high-temperature and high-humidity air and then is heated and transported to the first chamber and blown into the drying room by the first fan; Similarly, when the first fan rotates reversely and the second fan rotates reversely, slide the total heat exchanger to the third air outlet; Furthermore, it can be realized that the moisture exhaust effects of the hot air circulating in two directions inside the integrated dryer are relatively similar, improving the moisture exhaust efficiency of the drying room.

[0038] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the following-described embodiments are some embodiments of the present utility model, not all embodiments.

[0039] Refer to Figures 1 to 4 As shown, the following embodiments are made for the integrated dryer of the embodiment of the present utility model.

[0040] Refer to Figure 1 And Figure 2 As shown, the integrated dryer includes a housing 100, a condenser 200, a total heat exchanger 300, a first fan 400, a second fan 500, a third fan 600, and a fourth fan 700.

[0041] A first chamber 110 and a second chamber 120 are provided inside the housing 100. The first chamber 110 is located in front of the second chamber 120. A first air inlet 111 and a second air inlet 112 are provided on the front side of the first chamber 110. Both the first air inlet 111 and the second air inlet 112 communicate with the outside.

[0042] A third air inlet 121 and a fourth air inlet 122 are provided on the front side of the second chamber 120. Both the third air inlet 121 and the fourth air inlet 122 communicate with the first chamber 110. Moreover, the third air inlet 121 is located behind the first air inlet 111, and the fourth air inlet 122 is located behind the second air inlet 112.

[0043] The condenser 200 is provided in the first chamber 110. The total heat exchanger 300 is slidably connected to the housing 100. The total heat exchanger 300 slides in the left-right direction. After the total heat exchanger 300 slides left and right, it can move behind the third air inlet 121 or the fourth air inlet 122.

[0044] The total heat exchanger 300 generally refers to a fresh air and exhaust air ventilation device containing a total heat exchange core. The working principle of the total heat exchanger 300 is as follows: when the exhaust air in the moisture exhaust channel and the fresh air in the fresh air channel flow through the heat exchanger core in a positive cross-flow manner respectively, due to the temperature difference and vapor partial pressure difference between the airflows on both sides of the air flow partition plate, heat and mass transfer phenomena occur when the two airflows pass through the partition plate, causing a total heat exchange process.

[0045] The total heat exchanger 300 is provided with a moisture exhaust channel, one end of the moisture exhaust channel communicates with the second chamber 120, and the other end communicates with the outside.

[0046] The total heat exchanger 300 is also provided with a fresh air channel, one end of the fresh air channel communicates with the second chamber 120, and the other end communicates with the outside. Moreover, the fresh air channel and the moisture exhaust channel are separately arranged, and the airflows in the fresh air channel and the moisture exhaust channel perform heat exchange.

[0047] The first fan 400 is arranged at the first air outlet 111, and the second fan 500 is arranged at the second air outlet 112. Both the first fan 400 and the second fan 500 can rotate forward or backward.

[0048] In this embodiment, when the first fan 400 and the second fan 500 rotate forward, the first fan 400 blows air into the drying room, and the second fan 500 blows the air in the drying room into the first chamber 110, so as to form a circulating airflow in the drying room. And the air in the first chamber 110 flows through the condenser 200, and the condenser 200 heats the air in the first chamber 110, so as to form hot air and blow it out into the drying room.

[0049] In this embodiment, when the first fan 400 and the second fan 500 rotate backward, the second fan 500 blows air into the drying room, and the first fan 400 blows the air in the drying room into the first chamber 110, so as to form a circulating airflow in another direction in the drying room. And the air in the first chamber 110 flows through the condenser 200, and the condenser 200 heats the air in the first chamber 110, so as to form hot air and blow it out into the drying room.

[0050] The third fan 600 is arranged in the moisture exhaust channel, and the fourth fan 700 is arranged in the fresh air channel.

[0051] After connecting the integrated dryer to the drying room, the forward or reverse rotation of the first fan 400 and the second fan 500 can form hot air flowing in two different directions in the drying room; when the first fan 400 rotates forward to blow hot air from the first air outlet 111 into the drying room, the second fan 500 rotates forward to blow hot air from the second air outlet 112 into the first chamber 110 and blow part of the hot air from the fourth air outlet 122 into the second chamber. Slide the total heat exchanger 300 to the fourth air outlet 122 so that the third fan 600 can blow the hot air flowing into the second chamber 120 from the fourth air outlet 122 into the moisture exhaust passage and discharge it to the outside, discharging the high-temperature and high-humidity air to the outside and completing the moisture exhaust function. The fourth fan 700 sucks the dry air from the outside into the second chamber 120 through the fresh air passage and flows to the first chamber 110 through the third air outlet 121. Since the fresh air passage exchanges heat with the moisture exhaust passage, the dry air absorbs the heat of the high-temperature and high-humidity air and is heated and then transported to the first chamber 110 and blown into the drying room by the first fan 400; similarly, when the first fan 400 rotates reversely and the second fan 500 rotates reversely, slide the total heat exchanger 300 to the third air outlet 121; thus, the moisture exhaust effects of the hot air flowing in two directions inside the integrated dryer can be relatively similar, improving the moisture exhaust efficiency of the drying room.

[0052] In some embodiments, referring to Figure 2 With Figure 4 As shown, the moisture exhaust passage is provided with a fifth air outlet 310 and a sixth air outlet 320. The fifth air outlet 310 is communicated with the second chamber 120, and the sixth air outlet 320 is communicated with the outside. The total heat exchanger 300 slides in the left-right direction so that the fifth air outlet 310 faces the third air outlet 121 or the fourth air outlet 122.

[0053] After the total heat exchanger 300 slides, the fifth air outlet 310 faces the third air outlet 121 or the fourth air outlet 122, so that the high-temperature and high-humidity air blown out from the third air outlet 121 or the fourth air outlet 122 can directly flow into the fifth air outlet 310, ensuring that the high-temperature and high-humidity air blown out from the third air outlet 121 or the fourth air outlet 122 is discharged to the outside through the moisture exhaust passage, so that the high-temperature and high-humidity air in the moisture exhaust passage exchanges heat with the dry cold air in the fresh air passage.

[0054] In some embodiments, referring to Figure 2 With Figure 4 As shown, an opening 101 is provided at the rear side of the housing 100. The opening 101 extends in the left-right direction. The total heat exchanger 300 is slidably arranged in the opening 101. The total heat exchanger 300 slides in the left-right direction. Telescopic covers are respectively provided on the left and right sides of the total heat exchanger 300 to seal the space between the left and right sides of the total heat exchanger 300 and the edge of the opening 101.

[0055] The fifth air outlet 310 of the moisture exhaust passage is provided on the front side of the total heat exchanger 300, and the sixth air outlet 320 of the moisture exhaust passage is provided on the upper side of the total heat exchanger 300, and the sixth air outlet 320 is located outside the housing 100, so that the high-temperature and high-humidity air blown out from the third air outlet 121 or the fourth air outlet 122 can directly flow into the fifth air outlet 310, and the high-temperature and high-humidity air flowing through the moisture exhaust passage is discharged from the sixth air outlet 320 on the upper side of the total heat exchanger 300.

[0056] The fresh air passage is provided with a seventh air outlet 330, the seventh air outlet 330 is provided on the rear side of the total heat exchanger 300, the seventh air outlet 330 communicates with the outside, the fresh air passage is provided with an eighth air outlet 340, the eighth air outlet 340 is provided on the left and right sides of the total heat exchanger 300, and the eighth air outlet 340 communicates with the second chamber 120, so that the dry cold air outside can flow into the fresh air passage from the seventh air outlet 330, and the high-temperature and high-humidity air in the moisture exhaust passage and the dry cold air in the fresh air passage perform heat exchange, and finally the dry cold air flows into the second chamber 120 from the left or right side of the total heat exchanger 300 and flows to the first chamber 110.

[0057] The fifth air outlet 310, the sixth air outlet 320, the seventh air outlet 330 and the eighth air outlet 340 are reasonably arranged, so that the high-temperature and high-humidity air blown out from the third air outlet 121 or the fourth air outlet 122 can directly flow into the fifth air outlet 310, so that the dry cold air outside flows to the second chamber 120 through the eighth air outlet 340 of the fresh air passage, and the dry cold air blown to the second chamber 120 by the eighth air outlet 340 flows in the left-right direction, and the fifth air outlet 310 faces the third air outlet 121 or the fourth air outlet 122 that blows out the high-temperature and high-humidity air, so as to prevent the dry cold air from obstructing the flow of the high-temperature and high-humidity air in the second chamber 120.

[0058] In some embodiments, referring to Figure 1 and Figure 2 as shown, the fifth air outlet 310 on the front side of the total heat exchanger 300 abuts against the front inner wall of the second chamber 120.

[0059] The front inner wall of the second chamber 120 closes the total heat exchanger 300 to ensure that all the high-temperature and high-humidity air blown out from the third air outlet 121 or the fourth air outlet 122 flows to the fifth air outlet 310 and prevent the high-temperature and high-humidity air from entering the second chamber 120.

[0060] In some embodiments, referring to Figure 1 , Figure 2 , Figure 4 as shown, the third fan 600 is installed at the sixth air outlet 320, and the fourth fan 700 is provided at the eighth air outlet 340.

[0061] The third fan 600 is located at the sixth air outlet 320 of the moisture exhaust passage. The third fan 600 blows out high-temperature and high-humidity air outward at the sixth air outlet 320, causing the high-temperature and high-humidity air to be discharged upward. The fourth fan 700 is located at the eighth air outlet 340 of the fresh air passage. The fourth fan 700 blows dry cold air preheated by the high-temperature and high-humidity air passing through the moisture exhaust passage into the second chamber 120 at the eighth air outlet 340. The external dry cold air is sucked into the fresh air passage by the seventh air outlet 330 due to the negative pressure formed by the fresh air passage, preventing the seventh air outlet 330 from directly sucking in the high-temperature and high-humidity air discharged from the sixth air outlet 320.

[0062] In some embodiments, referring to Figure 2 With Figure 4 As shown, the fresh air passage is provided with two eighth air outlets 340, which are respectively arranged on the left and right sides of the total heat exchanger 300, and two fourth fans 700 are correspondingly arranged at the two eighth air outlets 340.

[0063] When the total heat exchanger 300 moves to the left so that the fifth air outlet 310 faces the third air outlet 121, the fourth fan 700 on the right side of the total heat exchanger 300 starts to blow out the preheated dry cold air to the right, so that the dry cold air flows into the first chamber 110 through the fourth air outlet 122; when the total heat exchanger 300 moves to the right so that the fifth air outlet 310 faces the fourth air outlet 122, the fourth fan 700 on the left side of the total heat exchanger 300 starts to blow out the preheated dry cold air to the left, so that the dry cold air flows into the first chamber 110 through the third air outlet 121.

[0064] In some embodiments, the integrated dryer further includes a first gate 130 and a controller. The first gate 130 is arranged in the first chamber 110. The first gate 130 separates the first air outlet 111 and the second air outlet 112 into two regions, and the controller controls the opening degree of the first gate 130.

[0065] When the moisture exhaust function has not been operated, the controller controls the first gate 130 to be fully opened, and the controller turns off the third fan 600 and the fourth fan 700, so that the hot air in the drying room circulates through the first chamber 110, reducing the entry of the hot air in the first chamber 110 into the second chamber 120; after the moisture exhaust function is operated, the controller can reduce the opening degree of the first gate 130, and the controller turns on the third fan 600 and the fourth fan 700, allowing part of the high-temperature and high-humidity air in the first chamber 110 to be discharged to the outside through the total heat exchanger 300; the greater the air humidity in the drying room, the smaller the opening degree of the first gate 130 controlled by the controller, increasing the flow rate of the high-temperature and high-humidity air in the first chamber 110 flowing into the total heat exchanger 300 to quickly reduce the humidity in the drying room.

[0066] In some embodiments, referring to Figure 2As shown, the integrated dryer further includes a second gate 140 and a third gate 150. The second gate 140 is disposed at the third air outlet 121, and the third gate 150 is disposed at the fourth air outlet 122. The controller controls the respective opening degrees of the second gate 140 and the third gate 150.

[0067] When the humidity in the drying chamber is relatively high, the controller increases the opening degrees of the second gate 140 and the third gate 150 to increase the amount of high-temperature and high-humidity air discharged to the outside and increase the amount of dry cold air flowing into the first chamber 110, thereby quickly reducing the humidity in the drying chamber; when the humidity in the drying chamber is relatively low, the controller reduces the opening degrees of the second gate 140 and the third gate 150, thereby reducing the amount of high-temperature and high-humidity air discharged to the outside and reducing the amount of dry cold air flowing into the first chamber 110, and reducing the heat loss in the drying chamber.

[0068] In some embodiments, referring to Figure 2 As shown, the condenser 200 is provided with two heat exchange plates 210. The heat exchange plates 210 dissipate heat outward to increase the air temperature in the first chamber 110. The two heat exchange plates 210 are disposed on the left and right sides of the first gate 130.

[0069] The heat exchange plates 210 are respectively disposed on the left and right sides of the first gate 130. Whether the first fan 400 and the second fan 500 rotate forward or backward, the high-temperature and high-humidity air is blocked by the first gate 130. Before the high-temperature and high-humidity air flows into the second chamber 120 from the third air outlet 121 or the fourth air outlet 122, it passes through the heating of the heat exchange plates 210, avoiding the cooling of the high-temperature and high-humidity air in the first chamber 110 and affecting the subsequent heat exchange efficiency; moreover, the dry cold air entering the first chamber 110 from the second chamber 120 also needs to be heated by the other heat exchange plate 210 to increase the temperature, reducing the influence degree of the dry cold air on the hot air temperature in the drying chamber.

[0070] In some embodiments, referring to Figure 1 As shown, the integrated dryer further includes a partition 160 and an evaporator. The partition 160 is disposed in the second chamber 120. The partition 160 divides the second chamber 120 into an upper part and a lower part. The third air outlet 121 and the fourth air outlet 122 are disposed in the lower part, and the evaporator is disposed in the upper part.

[0071] Avoiding the influence of the heat absorption capacity of the evaporator on the air flowing through the third air outlet 121 and the fourth air outlet 122.

[0072] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge of those of ordinary skill in the art.
